SPECIFICATION forming part of Letters Patent NO. 601,341, dated IEarch. 29, 1898.

Application filed May 12, 1897. Serial No. 636,174. (No model.)

To rtZZ whom it 7nd concern:

Be it known that 1, JAMES R. HAZELEY, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Time-Locks, of which the following is a specification.

.iy invention is more particularly a timelock for toy savings-banks; and its objects are, first, to provide a simple and efficient lock which may be set to run for any desired period of time within a certain limit; second, to provide simple and efiicient means for increasing the time for which the lock has been set after the bank has been closed and the time limited has begun to run, and, third, to provide simple and efficient means for preventing a decrease of the time limited after the bank has been closed or to prevent tampering with the mechanism and opening the bank within the period for which the lock has been set. These ends are attained by the mechanism illustrated in the accompanying drawings, of which- Figure 1 is a front elevation of a time savingsbank embodying the invention. Fig. 2 is an interior View, in end elevation, illustrating the arrangement of the money-drawer and safe. Fig. 3 is a front elevation of the interior mechanism, the casing being broken away for the purpose of illustration. Fig. at is a plan view, partially in section, the clock and a section of the casing being broken away for the purpose of illustration. Fig. 5 is an end elevation of the interior mechanism illustrated in front elevation in Fig. 3. Fig. 6 is a plan view of the mechanism for actuating the locking-bolts. Fig. 7 is a longitudinal sectional view of the mechanism for increasing the time limit and for preventing the decrease thereof. Fig. 7 is a view on the line CL CL of Fig. 7, and Fig. 8 is a side view of the latch-bolt shown in operative position in Figs. 4: and 7.

Referring to the drawings, a clock of ordinary construction is supported by a frame 1, which is secured to the casing-frame 2 by means of blank-headed bolts 3,passed through the lugs a of the casingframe and held in place by nuts 5, which are covered by the clock-face (3. The use of the blank-headed bolts having their nuts covered by the clockface, which is clamped in place by the casing 6, prevents the detachment of the clock from the locking mechanism, which would otherwise be readily accomplished and the movement thus tampered with.

The usual spring 7 and pinion 8 drive the lock-train, the pinion S gearing with a small pinion 9, which is fixed on an arbor 10, journaled in a bearing 11 of the casing-frame. The revolving arbor has a small pinion 12 fixed thereon, which gears with a large pinion 13, revolving it and the small pinion 14, fixed thereto, on an arbor 15, supported by the casing-frame. The pinion 14 gears with a large pinion 16, revolving it and a small pinion 17, fixed thereto, on an arbor 18, supported by the casingframe. The pinion 17 gears with and revolves the large pinion 19, having the hub 20, which rotates upon an arbor 21, fixed 'in the hub 22 of the casing-frame, the mechanism described being supported on the safelid 23. The end of the hub is provided with four holes 2%, which are placed about the axis of the hub equidistant therefrom and from each other.

Abarrel 25, having a worm or screw-threaded section 26, is journaled in a casing or cover 27, having bearings 28 therefor. A shaft 29, having a screw threaded end 30, extends through the barrel and into the hub 20, the shaft being permitted longitudinal movement within the hub and being prevented from revolving independently thereof by means of a pin 31, fixed in said shaft, which moves longitudinally in a channel 32, formed in the barrel, said pin and channel limiting the backward movement of said shaft. The pin 31 projects through the shaft and plays in a recess 35, formed in a bolt 33, which is adapted to reciprocate in a channel 32, formed in the barrel, the pin being designed to draw the bolt back a limited distance, while the recess permits the bolt further backward movement after the pin has reached its limit or the end of the channel 32. A coiled spring 36 lies in the bottom of the channel 32 and behind the bolt 33, which it tends to thrust forward into one of the holes 24 when presented, while the beveled face 34L on the outer end of the bolt provides means for forcing the bolt out of the hole 24 which it may occupy, permit ting the barrel 25 to be turned to the right independently of the hub 20 and preventing it from being turned to the left, the pin 31 being designed to draw the bolt back to the inner limit only of the beveled face 34 and its total withdrawal being effected by screwing the key 37 on the end of the shaft 29, which when turned to the right rotates the shaft, but when turned to the left merely detaches itself. Provision is thus made for retarding the release of the lock.

The worm 26 engages the teeth of a gearwheel 39, which is fixed on an arbor 40, journaled in the safe-lid 23. Beneath the lid and fixed on the arbor 40 by means of a set-screw 40 is a wheel 41, provided with a dial 41, preferably placed on the periphery of the wheel. A notch 42 is formed in the periphery of said wheel, and a pawl or spring-arm 43 is secured to the face thereof at a fixed distance from said notch. he pawl has'its free end extending backward from said notch and elevated above the lower end of a pin 44, fixed in the lid, the pawl permitting the notched wheel to revolve continuously forward, for it will slip past the pin, but preventing its rotation backward beyond a limited are by engaging with the pin.

A shaft 45 is pivoted within the safe at 46 and has

arms

48 and 49 fixed thereon. Each arm 48 is provided with a bolt 50, which lies in a channel 51, formed in the upper end of the arm, the bolt having a slot 52, through which and the arm a pin 53 passes, securing the bolt in position, but permitting it limited backward movement against the action of a spring 54, secured to the arm. A nose 55 on the bolt is adapted to engage a catch 56 on the lid to lock the safe, as illustrated in Fig.

0. Both the nose and the catch have their outer faces beveled, so that the latter descending and striking the former may thrust it back against the action of the spring, which restores the bolt to its normal position and locks the lid when the catch has passed the nose.

The arm 49 has its top 49 beveled to conform to the notch 42, into which it is forced by a spring 47, secured to the arm and hearing against the front wall of the safe, when the notch in its revolution is brought into registration with the arm. During the revolution of the wheel 41 through its entire are its periphery holds the arm 49 back, and thus, rocking the shaft 45 and the arms 48, looks the lid, as illustrated in Figs. 5 and 6; but when the notch at the end of a complete revolution of the wheel registers with the arm 49 the latter is thrown forward by its spring, thus rocking the shaft 45 and the arms 48, whereby the lid is released.

The position of the notch 42 with reference to the arm 49, and consequently the time of the release of the lock, is marked by a hand 57, which is fixed on the arbor 40 and travels over a dial 58, formed on the casing 27. The deposit is made by drawing out either of the drawers 59, which may be provided with bottoms (i0, pivoted at 61, so that when the drawer occupies the closed position the bottom drops down, as illustrated in Figs. 2 and 3, permitting the coin or other deposit to fall into the safe, and when the drawer is drawn out the bottom is thereby elevated and the passage to the safe closed.

In operation the lock-train may be constructed to effect a complete revolution of the notched wheel 41 and the consequent release of the lock at the expiration of any desired period of time, which for the purpose of illustration may be fixed at three hundred and sixty days. The lock-train is consequently so designed that the forty-eighttoothed pinion S operates a train consisting of a sixteen-toothed pinion 9, a twenty-toothed pinion 12, a sixty-toothed pinion 13, a twentytoothed pinion 14, an eighty-toothed pinion 16, a twenty-toothed pinion 17, and an eightytoothed pinion 19, which effects one revolution of the hub 20 and the barrel 25 in four days. The worm 26 on the barrel drives a ninety-toothed wheel 39, which revolves the notched wheel 41 through its entire arc in three hundred and sixty days, upon the expiration of which the lock releases through the operation of the arm 4?) in dropping into the notch and thereby withdrawing the bolts 50. If at any time during the period for which the lock has been set to run it is de-- sired to increase this time, this may be accomplished by screwing the key 37 on the shaft 29, drawing the shaft back to its limit, and then turning it to the right, thereby withdrawing the bolt 33 from the hole 24 with which it has engaged, and increasing the time by as many days as the bolt is turned through quadrants marked by the holes 24. If it is desired to have the lock release at the expiration of a month or other short period of time, the mechanism may be set to this time before the bank is closed by releasing the setscrew 40 and turning the wheel 41 until its notch 42 occupies the desired position relative to the arm 49, which position may readily be found by means of the dial 41.
